Bentgo Pantry 22-Piece Airtight Food Storage Containers
Lower concern. Hard plastics and silicone seals typically avoid PFAS, but no explicit brand disclosure.
Bentgo Pantry containers are rigid polypropylene food-storage boxes with silicone gaskets, materials not historically associated with intentional PFAS use. The brand does not publicly disclose PFAS testing or claims.

Why this grade

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Bentgo Pantry containers are polypropylene (PP, #5 plastic) with silicone gasket seals. Polypropylene is a rigid, chemically stable plastic that does not leach BPA or its replacements (BPS) under normal conditions and is rated safe for food contact by the FDA. The silicone seals are inert at room temperature and resist moisture degradation, making this material combination suitable for dry and moderately humid food storage.
The brand's record and disclosure
Waste Free Pantry (Bentgo's parent brand) markets these containers as BPA-free but has not published comprehensive material safety disclosures, third-party certifications (e.g., NSF, SCS), or responses to PFAS queries. No significant safety recalls or regulatory actions against this specific product line are publicly documented. The brand positions itself as eco-conscious but transparency on manufacturing standards and chemical testing remains minimal.
How it compares in its category
Polypropylene containers dominate the affordable food storage segment and are generally safer than older polycarbonate alternatives (which contained BPA). Bentgo Pantry sits mid-market: more transparent than unlabeled generic containers but less certified than premium brands offering NSF or FDA audits. Silicone seals are standard in this price tier and perform adequately for ambient storage; glass alternatives avoid plastic risks entirely but cost more and break easily.
If you buy it
Store only at room temperature or refrigerated; polypropylene softens above 120°F (49°C), so avoid dishwasher heat cycles and microwaving in these containers. Inspect seals annually for cracks or discoloration; silicone can degrade over 3-5 years with repeated washing. Wash by hand with mild soap and air dry to extend seal life. Replace containers if lids no longer seal effectively or if plastic shows cloudiness or stress fractures.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
BPA and BPS replacement chemicals
Manufacturer explicitly labels as BPA-free. Polypropylene formulations do not require BPA or bisphenol substitutes in production, and no public reports of BPS or other bisphenol contamination in Bentgo products exist.
Phthalate plasticizers
Polypropylene is inherently rigid and does not require phthalate plasticizers for flexibility; this hazard is not relevant to this material class.
Microplastics release from container degradation
Silicone seals can shed microparticles with age and repeated thermal cycling; polypropylene containers themselves are stable under normal storage but may fragment if dropped or exposed to prolonged UV light. Risk is low for indoor pantry use but increases with wear.
Silicone gasket degradation and mold growth
Silicone seals can trap moisture and develop mold or bacterial biofilm if not fully dried after washing, especially in humid climates. This is a maintenance issue rather than a manufacturing defect; proper air drying and periodic inspection are preventive.
Leaching from polypropylene at elevated temperature
While polypropylene is stable at room temperature, heating above 120°F can accelerate migration of residual monomers or processing additives into food. Avoid microwaving or dishwasher use with these containers.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
